Since the use of a bucket brigade, the objective of fire departments, in most cases, has been to get enough water on the fire to extinguish it. Because of advances in technology, the bucket brigade is no longer used. There are other methods that have been improved and tweaked in equipment, apparatus, and fire pumps. From the bucket brigade, departments went to fire pumps powered by humans. Then steamers replaced people, theoretically, because firefighters were not needed to operate the pump. Obviously there have been many more advances to the point that fire pumps today can deliver more water than most departments can apply on a fire-with only one person required to engage the pump.
Besides the fire pump, other elements of water delivery have improved. Synthetic hose has replaced cotton to improve efficiency and reduce friction loss and weight. Different diameter hose is available. Nozzles have been improved to deliver more water at reduced pressures to help with deployment and maneuverability. Water additives and foams have been developed to improve water's extinguishing capabilities. Water can be delivered in more ways than ever: through deck guns, elevated streams, special nozzles, and other specialty items.
So, you ask, what does this mean? There are a few things to think about and consider.
Increased Choices
Obviously there are many more choices to make today. Organizations need to study and investigate all their options and choose based on their circumstances. Not everything available will help improve every department's capabilities. Besides knowing capabilities, organizations need to know their limitations. They also need to understand the benefits being gained and whether or not these benefits are worth the cost.
As with virtually everything being done in today's fire service, training is more important than ever. Having the appropriate equipment does not get the water to the fire. Properly trained firefighters make that happen. They must be efficient and effective in their operation. They need to practice with all the components to the point that proficiency is maintained based on acceptable standards established by the department. The training must also include lessons in determining which options are best to use in various situations. Although the basic premise of getting water on the fire seems simple, the equipment, apparatus, and staffing available create multiple choices. Add to them the changing fire environment, including construction and contents, and you begin to see that the simple process of delivering water can be more complex when considering efficiency and effectiveness.
Water Delivery
Let's start with the apparatus and pump. What size pump do you really need on your vehicles? The trend is to get fire engines that deliver the most possible water, and most vehicles today exceed 1,500 gallons per minute (gpm). Although it may be difficult to argue against getting the most capacity as the cost of increasing pump size can be relatively small, organizations should at least consider their capabilities based on staffing and water supplies.
There are some organizations that, because of water supply limitations or inadequate staffing, cannot deliver 1,500 gpm from a single apparatus. To carry this further, they may not have a fire problem that requires this capability. But, I doubt if many departments consider their capabilities and try to match their equipment, apparatus, and personnel. This could be because it is a minor issue in the overall scope of the service. Yet a professional organization should not get in the habit of always doing what it has always done just because.
Hose Deployment
Deploying hose is something personnel should continually practice to improve efficiencies and time. Organizations should know the amount of time it will take to stretch various h
